...UPDATE! (08/07/2006) I did finally find one of the two long factory oil-lines that connects the 914-6 GT Front Mounted Oil-Cooler to the long Hard Brass Oil-Lines http://www.pbase.com/9146gt/image/45826047. The approximate length of this oil-line from end-to-end is 120 cm. or 47.6 inches (including connectors) while the girth or O.D. was measured at 31mm. For a quick conversion from centimeters to inches (or the other way around), please go here http://www.manuelsweb.com/in_cm.htm

Is this the same oil-line as used on the Collier 914-6 GT? Take a look here http://www.pbase.com/9146gt/image/26094131 - http://www.pbase.com/9146gt/image/26094121 - http://www.pbase.com/9146gt/image/22285874

Now, take a look at the "Alfa-Romeo" 914-6 GT (now owned by Jerry Seinfeld) http://www.pbase.com/9146gt/image/26886376 which clearly shows a very similar oil-line (I only say similar because I can not confirm the length, yet).

Lastly, how about the "Tiny-Naylor Family" 914-6 GT now owned by Ron Lockwood, look here http://www.pbase.com/9146gt/image/28198761 and here also http://www.pbase.com/9146gt/image/28198760 - I will try to obtain the correct Porsche part number.
